The reason why the freezer is called a freezer may be that its biggest function is to refrigerate it. Freezers can be divided into two types, household and commercial, and current can also be divided into two types, direct current and alternating current. Today we will talk about the 12V DC Freezer .
Direct current is also called constant current. Constant current is a type of direct current, which is a direct current with the same size and direction. Direct current is the unidirectional flow or movement of electric charge, usually electrons. The current density changes with time, but the direction of movement is usually the same at all times.
The direct current freezer has a simple structure, high efficiency, and good moisturizing effect. DC freezers are generally frequency conversion or electronic temperature control. They have better functions than ordinary refrigerators and are more convenient to operate.
Many mini car freezer use direct current instead of alternating current because electricity is relatively convenient. chinafreezers.com
